# Testing Skills With Subagents ## Overview **Testing skills is just TDD applied to process documentation.** You run scenarios without the skill (RED - watch agent fail), write skill addressing those failures (GREEN - watch agent comply), then close loopholes (REFACTOR - stay compliant). **Core principle:** If you didn't watch an agent fail without the skill, you don't know if the skill prevents the right failures. **REQUIRED BACKGROUND:** You MUST understand test-driven-development before using this skill. That skill defines the fundamental RED-GREEN-REFACTOR cycle. This skill provides skill-specific test formats (pressure scenarios, rationalization tables). **Complete worked example:** See examples/CLAUDE_MD_TESTING.md for a full test campaign testing CLAUDE.md documentation variants. ## When to Use Test skills that: - Enforce discipline (TDD, testing requirements) - Have compliance costs (time, effort, rework) - Could be rationalized away ("just this once") - Contradict immediate goals (speed over quality) Don't test: - Pure reference skills (API docs, syntax guides) - Skills without rules to violate - Skills agents have no incentive to bypass ## TDD Mapping for Skill Testing | TDD Phase | Skill Testing | What You Do | |-----------|---------------|-------------| | **RED** | Baseline test | Run scenario WITHOUT skill, watch agent fail | | **Verify RED** | Capture rationalizations | Document exact failures verbatim | | **GREEN** | Write skill | Address specific ba
